Improvement in the manufacture of boxes



i WILLIAM H. ALLEN, OF NEW YORK, N. Y.

IMPROVEMENT IN THE MANIJFACTURE OF BOXES.

Specication forming part of Letters Patent No. 182,543, dated September 26, 1876; application filed June 12, 1876,

To all whom it may concern: Y

Be it known that I, WILLIAM H. ALLEN, of the city, county, and State of N eW York, have invented a new and useful Improvement in the Manufacture of Boxes,- which improvement is fully set forth in the following specication, reference being had to the accompanying drawings. y

The object'of my invention is to produce a box for packing or holding articles, such as blacking, tobacco, Ste., out of a cheap material which will be Water-prooi'. It consists in a novel method of making a box from leatherboard or leather paper, which material has a sufficient amount of ductility, elasticity, and compressibility to permit of its being struck u p into the desired shape by means of (a punch and die) pressure. It Will also permit of embossing or printing', and the 'material may be colored in` various shades. It is then coated vWith a thin shellac, which renders it oil and Water proof and hard.

In the annexed drawings, Figure l represents a cross-section of a punch and die, showing the method of forming and shaping the leather-board under pressure. Fig. 2 represents a cross-section of the leather-board after it has been taken from the die-press. Fig. 3 is a similar View. Fig. 4 is a cross-section of a box complete.

Similar letters of reference in the several figures indicate like parts.

In the manufacture of my invention I take a sheet of leather-board or leather paper, of the desired quality and thickness. This I cut into shape, and moisten slightly. It is then placed in a proper die, and pressure is applied until the leather board or paper has been formed, struck up, and compressed into shape, as shown in Fig. 2 or 3, when it will retain the shape thus given. The leather board or paper is then treated or covered with a thin oil, colored as desired; and then itis coated with shellac, which, when dry, gives to it a nice bright finish, hardens it, and makes it oil andwater proof'. If desired, the leather-board may then be printed upon.

Fig. 4 represents a box made out of three pieces of leather board or paper, which has been struck up or formed in dies, as above set lforth. c represents the bottom piece, e the inner piece or lining, and c the upper piece or cover.

If desired, the piece e, may be cemented to the piece c by means of shellac or glue.

If' desired, the leatherboard, formed as shown in Figs. 2 and 3, may be used for various purposes, such as forming the bottom or covers to paper boxes, or coversto jars for fruit, dto.

Having thusfully described the nature and operation of myinvention, What I claim as new, and desire to secure by Letters Patent, is-

The proce ss herein described ofV manufacturing boxes or covers from leather-board, rendering the same Water or oil proof and hard, substantially as herein set forth.
